In a statement issued two days ago, the NASL called on its loyalists to head to the "squares of the revolution" – Tahrir, Rabaa Al-Adaweya and Nahda – to commemorate the memory of those who were killed on 14 August 2013.

While stressing peaceful means of protesting, the statement affirmed calls for "retribution" and the trying of "the coup leaders" who they described as guilty of genocide against Egyptians.

Meanwhile, security forces have said they will intensify their presence across the nation on Thursday.

The forceful dispersal by security forces of the two main pro-Mohamed Morsi camps in Cairo's Rabaa and Giza's Nahda squares claimed the lives of hundreds, according to government figures.

The dispersals were followed by nationwide violence that, according to a report issued by the National Council for Human Rights, reached 22 Egyptian governorates, with attacks on police stations and churches.
